Therapeutic vegetable substances

ABSTRACT

A product containing papain, bromelain or mixtures thereof is intended for use as a medicinal product at a dosage of at least 5000 mg administered for at least one day in a single dose. This dosage relates to papain powder having a titer of 3 U/mg and bromelain powder having a titer of 2 U/mg, and to a patient with a body weight of 55 kg. In the case of variations of the titer and/or of the patient&#39;s weight, the dosage must be varied in proportion to said variations.

The present invention relates to the therapeutic use of vegetable substances, and in particular of papain, bromelain and mixtures thereof.

Vegetable papain consists of several proteolytic enzymes, whose specific action is the hydrolysis of proteins, producing low molecular weight peptides.

As it is known, the enzymes are catalysts that are extremely active in biological reactions and belong to the chemical category of proteins, with chemical groups that can be of a non-protein nature (apoenzyme, the protein part; coenzyme, the non-protein component, especially vitamins and metals).

The enzymes have the character of specificity, and are named on the basis of the substrate on which they act.

The active site of an enzyme consists of a group of amino acids, which are not necessarily positioned in sequence on the polypeptide chain.

The amino acids are essential for human beings, as they make up the sequences of the proteins, as well as of non-protein peptides.

The amino acids are used by cells as nutrients, and are the basis of fundamental physiological activities. They are molecules that contain a COOH— group and an amino group NH₂—, joined to one and the same carbon atom C, the alpha carbon with respect to the carboxyl.

With respect to amino acids, the proteins are polymers of condensation of L,alpha amino acids, joined together in long chains by peptide bonds, with a number of proteins that can be extremely large, with L,alpha amino acids combined in various configurations: unknown, with polypeptide chains of helical shape, with folding of the helices with participation of hydrogen bridges.

About 22 amino acids are present in the human body: 8 of these are considered essential, so defined because they are not produced by the human body, but are only obtained from the diet.

Vegetable papain can be considered to be derived from complexes of amino acids with sequences characteristic of papain: lysine, threonine, valine, thionine, leucine, isoleucine, phenylalanine, histidine, arginine, oxyproline, aspartic acid, serine, glutamic acid, proline, alanine, cystine, tyrosine and others.

In the unripe, acidic fruit of Carica papaya there are 20 of the 22 amino acids, including 7 of the 8 regarded as essential. The phenylalanine contained in Carica papaya is among the precursors of substances with antidepressant action. These elementary amino acids can then naturally give rise to an enormous number of amino acid complexes of high molecular weight that are derived from individual amino acids by interaction of various forces: van der Waals, dipole-dipole interactions, particularly hydrogen bonds, ionic bonds.

The aim of the present invention is to use the properties of papain and of bromelain appropriately for therapeutic purposes.

This aim is achieved with a product containing papain, bromelain or mixtures thereof for use as a medicinal product at a dosage of at least 5000 mg administered for at least one day in a single dose, said dosage being referred respectively to papain powder having a titre of 3 U/mg and to bromelain powder having a titre of 2 U/mg, and to a patient with a body weight of 55 kg.

“Product containing papain, bromelain or mixtures thereof” means, in the present description, any product, in particular a drug, containing at least one of the aforementioned compounds with any degree of purity or titre and/or mixed with other substances.

It goes without saying that, in the case of variations of the titre and/or of the patient's weight, the dosage must be adjusted in proportion to said variations.

Advantageously, the papain is obtained from the unripe, sour, green fruits of Carica papaya.

Vegetable papain has the following characteristics:

-   -   powder with titre of about 3 U/mg,     -   MW of about 23 000,         where 1 U corresponds to the amount of papain that hydrolyses 1         micromole of N-alpha-benzoyl-L-arginine ethyl ester         hydrochloride per minute at pH 6.2 at 25° C. Stable at 2-8° C.

The vegetable bromelain used (from pineapple) has the following characteristics:

-   -   powder with titre of about 2 U/mg     -   MW of about 28 000,         where 1 U corresponds to the amount of bromelain that hydrolyses         1 micromole of 4-nitrophenol per minute at pH 4.6 and 25° C.         with the substrate N-alpha-carbobenzoyl-L-lysine-4-nitrophenyl         ester.

The product with the dosage of the invention has a therapeutic effect against every form of benign and malignant tumour, both undergoing metastasis, and with low or zero toxicity, and against other non-tumoral diseases, with the warning to avoid the treatment of patients undergoing dialysis and women who are or are suspected of being pregnant.

Among the neoplastic diseases that are treatable, we may mention benign and malignant tumours of any kind, for example of the oral cavity, lymphoma, cerebrocerebellar neoplasias (ependymoma, medulloblastoma, gliomas), of the uterus, fibromas, of the breast, of the vertebral column, of the intestine, of the colon and rectum, of the prostate, lung, gastric, of the liver, of the pancreas, of the gallbladder, of the oesophagus, of the stomach, of the bladder, of the kidney, bone, melanoma, of the ovaries and of the testes.

Among the non-tumoral diseases that are treatable we may mention leukaemias, thyroid, multiple sclerosis, pneumonia, polyarthritis, osteomyelitis, diabetes mellitus, diseases of the circulatory system, diseases of the nervous system, infections of any nature, in particular pulmonary, varicoses, hepatic cirrhosis, leprosy, AIDS, autoimmune diseases, infarction, stroke, ALS and Parkinson's disease.

The product with the dosage of the present invention is usable not only in human beings, but also in animals, as well as concomitantly with other plant or animal enzymes, such as chymotrypsin, trypsin, pancreatin etc., and/or chemotherapeutic, herbal and dietetic agents and drugs, vegetable and synthetic active principles, and food supplements.

According to the invention, the daily dose of papain, bromelain and mixtures thereof is preferably at least 14000 mg, and even more preferably is between 14000 and 20000 mg. For particularly weak or debilitated patients, having for example low blood pressure or heart disorders, the preferred daily dose is between 5000 and 7000 mg and is administered for at least four consecutive days.

If necessary, administration of papain and bromelain can be combined with the administration of specific compounds, which avoid problems connected with the high single dose of administration of papain/bromelain per day (24 hours), and are at the same time able to activate the cellular selectivity directed solely at infected cells and metastases in progress.

These compounds—for example calcium chloride, potassium chloride, sodium chloride, calcium sulphate, silica—can be energized beforehand by exposure to low-intensity magnetic fields and then stabilized.

These compounds in aqueous dilution or dispersion of 1 to 1000 can be administered in amounts between 30 and 70% of that of papain and bromelain, in particular about 50%.

Treatment against carcinogenic cells is initiated with a single dose per day (24 hours), repeating it after 24 hours, then increasing it up to the limit of tolerability of the healthy tissue or organ compared to that which is carcinogenic.

After patients took a single daily dose of 14 000-20 000 milligrams of papain, values of blood pressure, degree of hydration and heart rate were observed in the normal range, already with results that were positive therapeutically.

It is also possible to administer adjuvant substances simultaneously, such as vitamin C, low doses of cortisone, plant complexes for energy, mineral salts, antiviral and antibacterial agents.

After a first single administration of 14 000-20 000 milligrams of pure papain in 24 hours, it is possible to extend the treatment for 7 days with 1500 mg of papain daily, then on alternate days for seven times with 1500 mg of papain administered per day, and, after a pause of one week, again on alternate days for seven times with 1500 mg of papain administered per day.

The final result was excellent therapeutically. The values obtained 20/30 days after completion of the whole therapy on subjects who previously had an approximate CEA value between 1000 and 2000, were CEA 2 and CA125 1.5.

The patient receives a quick benefit immediately after beginning administration of the product, even if the analytical test values determined with the current methods are subject to interference and therefore the values are inaccurate during the administrations. It is necessary to wait 20/30 days after the end of the administrations to obtain actual values.

The product according to the dosage of the present invention can also be applied at an advanced stage of chemotherapy, radiotherapy, surgery etc.

It can be seen from the foregoing that the present patent description protects any therapy of every type of benign or malignant tumour undergoing metastasis, as well as of any type of non-cancerous pathology, even not mentioned.

The present patent description aims to protect the studies and experiments conducted for several years about the use of papain/bromelain, pure or at varying degree of concentration—and optionally with addition of synchronizing compounds, or mixed with other plant or animal enzymes or plant or synthetic active principles, whether or not antitumour, whether or not concomitantly with chemotherapeutic, herbal and dietetic agents and drugs—at a high daily dose never previously investigated or patented, in the treatment of benign or malignant tumours, of the diseases mentioned above and of any other pathology not expressly mentioned, requiring therapeutic application of high daily doses of papain/bromelain that were the subject of the aforementioned research and experiments.

The present patent description aims to protect the production, commercialization, sale to public or private health services or individually of products based on more or less pure papain/bromelain or mixed with any other enzyme or pharmaceutical, chemical, herbal, dietetic product or plant or synthetic active principles, food supplements used at the high daily doses stated above according to the present patent, expressed in pure papain/bromelain or at the concentration already stated above, or other concentration.

As already mentioned, the present invention also finds application in the veterinary field, in parallel with all the applications mentioned above for human beings.

The present patent description aims to protect the production, commercialization, and marketing of drugs, food supplements, herbal products, dietetic products, plant or chemical active principles, based on vegetable papain/bromelain, pure or synchronized, or compounds based on pure vegetable papain/bromelain mixed with other plant or animal enzymes already known for experimentation and commercialization (such as chymotrypsin, trypsin, pancreatin and others) with the intention and indication of using them at the high daily doses mentioned above in pure papain, or pure bromelain, or at various concentrations.

The present patent description aims to protect the research and experimentation conducted into the therapeutic use of papain/bromelain at high daily dose, not previously patented or investigated, as vegetable papain/bromelain at the concentration specified above (or any other vegetable papain/bromelain at varying concentration, referred to the titre of that according to the present patent, taken daily), also for any type of non-cancerous pathology even not mentioned here.
